Beit known that I, FLETCHER D. SWANEY, a citizen' of the United States,residing atK'ansas City, in the county of Wyandotte and State of Kansas,have invented certain new and useful Improvements in Furnace or StoveFire-Pots, of which the following is a speciication.

My invention relates to fire-pots for hot-air ro furnaces andheating-stoves of that class in which air is supplied tothe fuel throughthe wall of the {ire-pot for the purpose of effecting a more thoroughand complete combustion and thereby economy in the useA of fuel, x5 andhas for its objects to produce a structure of theA character named whichcan be quickly and easily repaired without the assistance of skilledlabor and which is of simple, strong, durable, and comparatively cheapconstruczo tion.

To these ends the invention consists in certain novel and peculiarfeatures of construction and organization, as hereinafter described andclaimed, and in order that it may be fully understood reference is to behad to the accompanying drawings; in which- Figure l is a centralvertical section of the body of a stove or fire-pot shell of a furnace iequipped with a lire-pot embodying my in- Avention, said nre-pot beingalso shown in sec- -tion on the line I I of Fig. Fig..2 is ahorizontalsection taken on the line II II of Fig. 1. Fig. 3 is a horizontalsection' on the line III III of Fig. 1 with the grate removed. Fig;

35 4 is a vertical section taken on 'the dotted line IV of Fig. 2, butwith the sectional wall of the lire-pot omitted.l

In the said drawings, 1 designates whatA .4 designates a circularcasting riveted or otherwise secured in ahorizontal position to theshell 1 and provided in its upper side ver- 5o tically'below groove 3with an annular groove 5 and with a series of equidistant holes6,opening up communication between groove 5 and the ash-pit chamber below.The base of the groove is also provided between said holes withsubstantially parallel ribs 7, eX- tending approximately radially of thecasting, and depending from the inner margin of the latter atdiametrically opposite points are la pair of apertured angle-lugs 8, fora purpose which hereinafter appears. 6o

The wall of the re-pot' is composed of a plurality of sections', havingtheir lower ends ir1`.groove 5 contiguous to its inner wall and providedat their upper ends with laterally-projecting lugs 10 for the purpose of65, spacing the upper ends of the sections equidistantly, these spacesby preference growing gradually Wider toward their lower ends andconstituting slots 11, which admit air to the M shell and having itslower end between ribs 8o 7, which latter thus coperate with lugs 10forthefpurpose of holding the sections in their proper relativepositions.l The lower ends of said ribs are recessed, as at 13, to fitover the outer wall of groove 5, and their upper ends are recessed, asat 14, a sufficient distance to enable one grasping a section to raiseit in slot 3 until its lower end is above the plane of the inner wall ofgroove 5, and therefore in such position that said end may 9o be swunginwardly and the section readily withdrawn from the furnace.

15 designates theri'ng portion of the grate, the same resting uponcasting 4 and having y a slotted or skeleton portion 16 projecting 95downward and inward of the castingand provided to the rear of thecenterof the furnace with two or more inwardly-projecting lugs 17.

` 18 designates a cross-bar havingdownroo wardly-disposed hook ends 19engaging the apertured angle-lugs 8 and with a centralupwardly-projecting pivot 20, upon which is loosely mounted the rearsection 2l of the rotary portion of the grate, said section being alsosupported upon lugs 17, hereinbefore mentioned.

At opposite sides of its axis grate-section 21 is provided with openings22, bridged by cylindrical portions 23, forming hinge-rods for thedownwardly-disposed hooks 24 at the rear sid'e of the front section 25of the rotary portion of the grate, said section being formed centrallywith the arm 26, underlying grate portion 16 and projecting radiallyforward and almost through the tube 27, opening up communication withthe ash-pit, said tube being cast by preference with the doorcasing 28,to which the outer shell 29 of the air-chamber of the furnace isattached in the usual or any preferred manner.

To support the front half or hinged section of the grate in a horizontalposition, I employ a rod 30, extending across tube 27 and pivotedloosely at one end, as at 31, so as to swing in a horizontal plane, butwith some vertical play. The free end of said supporting-bar rests inthe angle-socket 32, cast with tube 27 by preference and having itsinner arm adapted to limit inward movement of said pivotedsupporting-bar and its outer arm sloping upwardly and outwardly tocompel said bar as swung outwardly to rise, and thereby slightly elevatethat portion of the fuel superimposed i, with reference to thehinge-section of the grate, this elevation resulting obviously in thepartial disintegration or loosening of the mass, to the end that whenbar 30 is swung from under arm 26 and the latter, with said hingedsection, drops to the position shown in dotted lines, Fig. 4, theclinkers or ashes at the bottom of said mass may fall or be easily drawnout by means of a poker through the opening into the ash-pit. In thismanipulation of rod 30 it is necessary to open door 33. The latter isprovided with a vertically-opening slot-covering door 34, and by openingthis door the poker can be inserted vand hooked over the free end of rod30 for the purpose of swinging the same forward to permit the grate todrop. Through said slot the operator also inserts a gas-pipe (not shown)orits equivalent to lit over or otherwise engage the end of arm 2G forthe purpose of shaking the grate in the usual manner, bar 30 of courseforming the support for the grate during such action.

For the purpose of removing or replacing one or more of the fire-potwall-sections, as hereiubefore explained, it is first necessary to dropthe front half of the grate part way, and then disengaging its hooks 24from hingerods 23 remove it from the furnace. The rear half of therotary portion of the grate is then removed in an obvious manner and bar18, too, if necessary. The operator can now reach in-if necessary, crawlin-and remove one or more of the wall'sections 9 and substitute others,or in lieu of removing the grate, as explained, the operator can reachin through the fuel-door opening (not shown) and substitute a good for adefective Wall-section.

The ring portion l5 of the grate may be formed in asingle piece, but ispreferably composed oE two sections abutting together at their ends,theweight and character of the ring serving to maintain these parts inproper relation to each otherand the remainder of the tirepot, the ringbeing made in halves to render it more convenient to be secured in orremoved from position and, furthermore, in case of injury to enable theowner to duplicate the defective part at a comparatively small expense.When all of the partsl are properly assembled and the fuel is burning onthe grate, it will be apparent that the air has access to the fuel notonly up through the grate, but also through openings 6 to theair-chambers between the fire-pot wall and shell and thence through theupright slots or air-spaces l1 into the body of the fuel, thepenetration of the air into the fuel at these various points resultingin a more perfect combustion and consequent economy of operation.

From the above description it will be apparent that I have produced afire-pot of the character mentioned which is of such simple constructionand organization that the owner of the furnace can make the necessaryrepairs about as easily and quickly as an eX- pert, and it is to beunderstood that while I have illustrated and described the preferredembodiment of the invention it is susceptible of modiiication in minorparticulars without departing from the essential spirit and scope orsacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is-
